Specification of Letters Patent.

Patented March 13, 1906.

Application filed September 18, 1905. Serial No. 279,022.

To all whom it may concern.-

Be it known that I, FRANK HINIKER, a citizen of the United States, and a resident of Chinese Cam in the county of Tuolurnne and State of Cali ornia, have invented certain new anduseful Improvements inBaling-Machines and I do declare the following to be a full,

' clear, and exact description of the invention,

having a larger feed-chamber than is now in use in machines of this character, also to produce a machine which will form a strong and compact bale. This object I accomplish by providing two reciprocating side pressingboxes and by such other and further combination of parts as will appear by a perusal of this specification and appended claims.

In the drawings similar characters of reference indicate corresponding parts in the several views.

In the drawings I have illustrated but one half of the machine, the other half being identical in all respects.

Figure 1 is a side view of the machine with the baling-chamber not shown. Fig. 2 is asectional view taken on a line :v of Fig. 1. Fig. 3 is a sectional view of the press-plunger. Fig. 4 is a sectional view taken relatively on a line y y of Fig. 1. Fig. 5 is a top plan view of the machine.

1 designates the supporting-beams of the machine. Arranged across said beams are two cross-beams 2, the whole being covered with a suitable flooring.

3 designates the baling-chamber, and 4 the plunger, seated in the usual box 5. In each side of the box 5 is a slot 6, and in each side of the plunger 4 is a coinciding slot 7. Near the outer end of each of the slots 6 is a small catch 8, curving toward the inner ends of the said slots. In each of the slots 7, near the inner ends thereof, is a small catch 9, similar to the catch 8. The purpose of these catches will be hereinafter shown.

10 is the feed-chamber, arranged on the beams 2. On each outer end thereof are secured two cross-pieces 11 and 12. Attached to the pieces 11 are inwardlyprojecting blocks 13, and from the pieces 12 are attached inwardly-projectmg blocks 14. On the inner ends of the blocks 14 are pulleys 15, and on the outer ends of the floor of the feed-chamher are pulleys 16. Located in the feedchamber 10 are two side presser-boxes 17, provided with rollers 18, which extend through the sides of the said boxes and bear on the sides and bottom of the said feedchamber.

19 represents blocks extending outward from the heads of the boxes 17 and provided with rollers 20 at their outer ends, which rollers bear between the blocks 13 and 14.

21 is a cable or chain connected to the outer ends of the blocks 19 and extending over the pulleys 1 5 and 16 and thence through a pulley 22, located under the center of the feed-chamber, and thence to the usual horsepower.

23 represents springs connecting the heads of the boxes 17 to the blocks 12.

24 represents substantially S-shaped retaining-hooks pivotally mounted on each side of the feed-chamber 10 and extending through said sides and bearing on the sides of the boxes 17 when the same are out and extending in position when the same are in. Said hooks are regulated by means of springs 25.

26 represents U shaped levers pivotally mounted on each side of the feed-chamber 10, said levers being linked to the hooks 24 at points near where said hooks enter said chamber.

27 represents links connecting each pair of levers 26.

28 represents levers linked to the sides of the chamber 10, which are on the same side as the plunger-box 5, said levers extending through the slots 6"and 7.

29 represents levers pivotally mounted and linked to the levers 28 at one end and. to the levers 26 at the other.

In using the machine the hay is fed into the chamber 10 in the usual way. By suitable horse-power applied to the cable 21 the boxes 17 are then pulled forward, forcing the hay to the center of said feedchamber. When the heads of said boxes 17 are in a line with the sides of the plunger-box and the bale-chamber, the springs 25 pull the retaining-hooks so that they extend into the chamber 10 back of the boxes 17, thus holding said boxes in position. The plunger 4 is then driven forward, pressing the hay into the baling-chamber 3, and as it goes forward the levers 28 slip over the catches 8, and as said plunger makes the back stroke it pulls said levers with it by means of the said catches 9.

This action pull on the levers 29, which ac- I ber, presser-boxes arranged therein, retaintion pulls the levers 26 outward and this pulls the retaining-hooks out of engagement with the boxes 17 and the springs 23 then pull the boxes 17 backward ready for another drive. When the levers 28 reach the catches 8, the curved portion thereof raises them and releases them from the catches 9, and the springs 25 then pull the whole system of levers into their normal position ready for another drive. Thus it will be seen that by providing the side presser-boxes 17 I have roduced a machine in which the feedchamber is larger than in the single straightplunger machines and that by the use of my machine a more compact bale can be pressed.

I have now entered into a detailed description of the construction and arrangement of parts embraced in the present and preferred embodiment of my invention. I do not desire, however, to be understood as confining myself to such detail, as many changes may be made in practice which fairly fall within the scope of my claims.

I claim as new and useful and desire to secure by Letters Patent 1. In a hay-baler a transverse feed-chamber, presser-boxes arranged therein, and a cable or chain connecting said presser-boxes to any ordinary horse-power, as specified.

2. In a hay-baler a transverse feed-chamber, presser-boxes arranged therein, means for pulling said boxes forward and backward, means for holding said boxes in the forward position while the plunger of said machine is making its stroke, and means for automatically releasing said boxes again, as set forth.

3. In a hay-baler a transverse feed-box having presser-boxes arranged therein, crosspieces arranged at each end of said chamber, means for pulling said presser-boxes forward, and springs pulling between the heads of said boxes and the said cross-pieces.
